Quoted from MJW:Did more research and confirmed these units will not operate once security key battery dies due to encryption. There is a guy who posted free hack info on you tube to put encryption on hard drive for games with 2011 software only. He also sells the service on ebay for $125 for people without the skill to hack. Without this upgrade these machines will not work once the security key battery dies. Wish. Would have know this when I bought my unit.
I didn't know this either when I bought mine. I have the 2013 Aurora version and unfortunately there isn't a hack for that version. When mine goes, I'm completely screwed from what I've read.
